l etented I July 14, 1931 EPATENT". OFFICE UNITED CARL .r. annennn'rm, or ALAMEDA, CALIFORNIA IL-CIRJOSSIN G Application filed November 29, 1930. Serial No. 499,008.

My invention relates generally to rail alone, and in other cases traific rails asso-.

ciated with guard rails, or with easer rails, or with both guard and easer rails.

A defect in this type of rail-crossing is the 10 wear between the rails and the'reintorcing bars which are fitted in. the several angles and connect the sections together, the fitting of said bars being usually by means of bolts. This wear results in a loss of rigidity in the 4 assemblage.

The object herein is to avoid this defect by welding the reinforcing bars to the rail sections, the preferred location of the weld seams being at top and bottom of said bars uniting them to the heads and bases of the rails.

In the accompanying drawings, I have illustrated my improvement as applied to the r several forms of built-up crossings, it being understood that changes may be made with-,

out departing from the spirit of the invention(1 a; defined by the claims hereunto apen e p In the drawings Fig. 1 is a topvplan View of a rail-crossingcomprising trafiic-rail sections, guard-rail sections and easer-rail sec tions, to which the reinforcing bars are applied by seam welding. 1

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a cross-section similar to Fig. 2 but showing also additional possible welds.

Fig. i is a cross-section showing the seam welded reinforcing bars applied directly to the trafi'ic-rail section in a crossing as would be the case where such sections alone were present.

Fig. 5 is a cross section of import similar to Fig. 4, but'in a crossing Wheretrafi'ic-rail sections and guard-rail sections are used, the reinforcing bars being welded to said rail sections respectively.

Fig. 6 is a cross section indicating the improved crossing where traflic rail and easera rail sections only are used, the reinforcing bars being welded to said rail sectionsrespectively. The crossingherein illustrated in Figs. 1, 2 and 3 is one form of the built-up type comprising associated short sections of trafficrails 1, guard rails 2, and easer rails 3; also filler blocks l, Fig 2, seated between the webs of said rail sections 1, 2 and 3; angle fitting reinforcing bars 5 in the webs of rail sections 2 and 3, on the side opposite the filler blocks; angle braces 6; and bolts 7 passing through said bars, rail sections and filler blocks. The entire crossing is mounted on plates 8 overlying the ties 9 and underlying the rail bases.

Experience has shown that the tightness or rigidity of the crossing assemblage, whatever its rail section composition maybe, and which it is the functionof bolts to impart, is; not permanent. Wear takes place between the bars and rail sections; and though this may be the casein even the simpler forms of built-up crossings, it is particularly'notices able between the angle-fitting reinforcing bar-stand the sections 2 and 3 of the guard and easer rails, respectively in the relatively complex form of Fig. 1.

The present improvement consists in seamwelding the reinforcing bars to the railsections in' all forms of crossings above referred to and herein illustrated, said welds in the several illustrations being indicated by the seams 19 between the upperportion ot the reinforcing bars and the adjacent heads of the rail sections and the seams 11 between the lower portion of said bars and the bases of said rail sections.

- In all the figures, in order to avoid confusion, the same reference numerals are used to 90 indicate like parts. In Fig. 4 the cross-section is indicative of a built-up crossing in which sections of trafic-rail alone are pres ent, one of said sections beingindicated by the numerall, to which, on each side thereof,

are fitted the reinforcing bars 5, seam welded at 10 and 11 to the head and base, respective- 1y,of said rail-section. V

In Fig. 5 a cross-section is shown of a built-up crossing in which a guard rail sec- W1 tion 2 is associated with the traflic rail section 1; a filler block 4 lying between them;

and the reinforcing bars 5- being fitted to the outer sides of said rail sections and welded thereto by seams 10 and 11. Similarly in the cross section Fig. 6, a crossing is indicated in which an easer-rail section 3 is associated with a traffic-rail section 1, filler block 4, and reinforcing bars 5 welded at 10 and 11.

Though the welding of the reinforcing bars to the adjacent rail sections is deemed suflicient for. the permanent tightness or rigidity of the assemblage, it is possible that further welding of other adjacent surfaces may contribute to the desired result. I have shown this inthe cross section Fig. 3, in which ap-- pear, in addition to the weld seams 10 and 11, above described, other weld seams, as for example seams 12 between heads of rails sections 1 and 3; and seams 13 welding the heads of rail sections 1 and 2 to the intervening filler block 4.

I claim 1. A rail-crossing of the built-up type comprising rail sections; and reinforcing .bars fitted to said rail sections in the intersecting angles of said sections,. said bars being welded to said rail sections.

2. A rail-crossing of the built-up type comprising rail sections; and reinforcing bars fitted to said rail sections in the intersecting angles of said sections, said bars being welded above and below to the heads and bases respectively of said rail sections.

' 3. A rail-crossing of the built-up type comprising rail sections; and reinforcing bars fitted to said rail sections in the intersecting angles of said sections; said bars being united to the heads and bases of said rail sections by weld seams extending along the upper and lower edges of the bars.

In testimony whereof I have signed my name to this specification.
